This study aims to investigate the most influential factors which dominant the flow ability, setting time and compressive strength of Na2SiO3-activated geopolymer mortar cured at ambient temperature. The factors include sodium silicate concentration, alkaline activator-to-binder ratio and slag content. A Taguchi orthogonal array was adopted to conduct the experiment and the S/N analysis was used to evaluate the significance of factors. Results show that sodium silicates concentration plays the most vital role on both workability and compressive strength among these above factors.
